    Paint's too thin / not sticking to the plastic.

    Hey.


    Ok so iv used revell and humbrol matt enamels before and they have always been fine with 1 coat.


    But iv got other colors here but they don't seem to be as thick and they don't stick to the model at all!


    No idea why but when i apply it with one stroke its fine, but then as soon as the brush touches the paint again it just moves it around.


    Anyone else seen this sort of madness? and more importantly how do you fix it?


    Atm i need to do 5 coats of revell matt enamel white just for it to cover the model without showing the plastic color, even then its only maybe 95% covered.

    As you can see its made for plastic models but with 5/6 coats needed i'm half way thought the tin and there's still a fair bit to paint lol.


    Would brushes have anything to do with it? i'm using these.

    [EDIT] With the quite ludicrous amounts of paint required to get a good coverage you end up losing a lot of the fine details.

    Have you give the paint a good stir, to make sure there is no pigment at the bottom of the tin. I don't like using these small tins myself, I usually use Zero paints or Vallejo acrylics.

      Do you wash the kit ? Sometimes there is some release agent present so the paint won't stick , if it persists you could use a primer

        As mentioned above, stir the paint like mad, add a primer coat and wash prior to painting-some folk do, and others don't-I do just to be sure. Also, the heat can also make thinner paints go off quicker and dry patchy.

          Shook it and got a matchstick in about it for a good 15minz, no improvement.

          No i did not. Good job im using enamels and not acrylics, a good bath in soapy water should remove any agent shouldn't it?


          Side thought, that would only stop the first coat going down, but it wouldn't effect the second+ coats?

            This one goes on thin and patchy. Seems like the paint's too thin and the models too oily or something :\

              Yeah mixing humbrol paint is a must , I use the revell and humbrol acrylics, there not as tough as enamel but I find they go on better and you can thin them with water

                No, the top bottom coat could still have some residue that will transfer to the top coat. Question: is the paint old? Could be that the pigment will not mix with the carrier properly, maybe get a new tin and try again.

                  White is a PITA to get down well. I always prime before painting white for that very reason. No fancypants primer either, just Poundlands finest which is excellent IMHO.


                  As Alan says, mixing is 90% of the battle. To save my aching hands I use a homemade battery mixer made from a nasal trimmer (courtesy of Poundland again!)

                    It will give a better second coat , if your brush painting it's best to thin your paint and put about three thin coats on , I use one of those syringes you get in calpol the kids medicine, I use between 5 and 10 ml depending on the thickness of the paint

                      Never liked Humbrol paints. There are much better modelling paints on the market these days. Get some decent paint and give it another go after you have made sure that the parts are clean. Good luck Jason

                        Just to add to what Patrick says, I use poundland primer and auto primer and they are great for coverage.

                          Agree, but sometimes you just need a tin of enamel-handy for Sci-fi builds, instruments, buttons etc.

                            Jason have you tried another paint or colour ?


                            Looks to me as though this is a faulty batch perhaps or it has been stored. Who knows.


                            Obviously there is something wrong and the above is the first port of call.


                            Have you tried this paint on another odd bit of plastic. If the same happens then you have proved it is defective paint.

                              Well the problematic paint in question is actually Revell Jason! And there's nothing wrong with Humbrol paints - enamels that is! Some of the newer batches are sometimes inconsistent, but unfortunately that's true of most manufacturers who've moved their production to China.
